CAR DOOR.

Application filed January 29, 1921. I Serial No. 440,988.

To all whom it may concern:

Be it known that I, I'IERMAN (I. Pinnnn, citizen of the United States,residing at Blue Island, in the county of Cook and State of Illinois,have invented a certain new and useful Improvement in Car Doors, ofwhich the following is a full, clear, concise, and exact description.

My invention relates to doors which are bodily movable in their ownplanes, suchas are employed, for example, in the sides of freight cars.In practicing my invention I employ mechanism for forcing the bodilymovement of a door in its own plane comprising one element in the formof a. block and another element in the form of a lever engaging theblock, one of these elements be ing carried by the door and the otherbeing mounted apart from the door upon one side thereof;

In accordance with one feature of my in vention the block is formed witha channel that receives the lever and is so shaped and disposed tocontain the lever in the various positions to which the lever is swungin movino the door and to have one side en- I y the lever whenthe leveris moved in a door opening direction and the opposite side engaged bythe lever when the lever is moved in a door closing direction.

In accordance with another characteristic of the invention the block isformed partially to overhang the lever 'when'the door is in a closedposition to enable the lever and the block to take part inholding thedoor closed. Where the block is formed with the described channel theoverhanging forma tionof the block keepsthe lever within the channeluntil the door has been sui'iiciently opened to permit the lever to passby the overhanging formation.

In the preferred embodiment of the in vention the channel in the blockis oblique and is margined at each side by an overhanging portion, bothoverhanging portions serving to maintain the lever and block in assemblywhen the door is closed and until the door is sufliciently open topermit movement of the lever between the overhanging portions, whichoverhanging portions have opposing edges that are obliquely arran 'edand spaced apart suflicently to permit the lever to be moved through thespace between these opposing edges when the lever has been sufficientlyswung in a door opening direction to bring it into alignment or registrywith the spacebetween said opposing oblique edges of said overhangingportions.

In accordance with another characteristic of the invention I swinginglymount the block upon the door so that it may be turned to serve as ahandle by which the door may also be moved, this featureof the inventionmaking it unnecessary to employ a special handle to continue themovement of the door in the portion of its travel where the lever couldnot have door moving engagement with thebloclr.

My invention may be employed in connection with a single door or adoubledoor, the accompanying drawings showing both of these embodiments of theinvention. In the drawings Fig. 1 illustrates a portion of a freight carin side elevation-with a single .door, provided with a door opening andclosing device of my invention, shown in closed position; Fig. 2illustrates a portion of a freight car in side elevation with a doubledoorprovided with a door opening and closing device of my invention,both doors being shown in closed positions in full lines and in slightlyopen positions in dotted lines; Fig.3 is a detail view on a larger scaleof the lower portions of the two doors in conjunction with a centralstop that defines the fixed meeting plane of the opposed edges of thedoors; Fig. 4 isa sectional view on line 44ifof Fig. 3g'Fig. 5' is asectional view on line 5-5 of Fig. 2; Fig. 6 is a view on a larger scaleillustrating the door open ing and closing mechanism of Fig. 1; Fig.

7 is a perspective view illustrating the door .moving. lever in dottedlines and the 00- operating block in full lines Fig. 8 is a sec 'tionalview on lineB-S of Fig. 6; Fig. 9 is a sectional View on hne 9-9 of Fig.6;

and Fig. 10 is a sectional view on line To -1O of Fig. 6. i I j Lil-1eparts are indicated by similar charactors of reference throughout thedifferent figures. H

The embodiment of, the invention illustrated in Figs. 1, 6, 8, 9 and 10will be first described, Fig. 7 being also referred to as the structurethere illustrated is common to both embodiments: of the invention.

The single door 1 is mounted to move bodily substantially in its ownplane, this door having rollers mounted at its top side that roll uponthe door' supporting track 8 which,

as illustrated, is mounted upon the sideof a freight car I. hen the dooris in posiv may swinging or tion to close the door opening in the sideof the car, one upright meeting edge thereof engages a face of theupright angle rail 5. This angle rail carries ears 6' and 7- whichoverlie the outer face of the door to hold it close to the side of thecar. 7 The door opening lever 8 is preferably rnounted apart from thedoor and upon one side thereof this lever being desirably pivoted; atitsupvper end to the ears 6. The block Qthat 00- operates with the lever isconsequently mounted upon the door. formed with a channel 10 thatreceives, the lever, this channel being, soshapedl and dis-' posed: asto contain the lever in the various. positions to which the lever isswungin moving the door and to have. one, side 11 thereof engaged by thelever therein when the lever isinoved in a door opening direc-. tion andthe other side 12 engaged by, the lever when the lever is moved in adoorclosing direction.

In the preferred embodiment o fthe in; vention thechannel is obliquelydisposed to reduce the lateral extent of the channel. as much aspossible to reducetofa minimum the looseness or lost motion of the leverwithin the channel; 7

The block is, formed with portions 18- and 1 1- which overhang thechannel 10iand the leverv therein, both overhanging portions serving tomaintain the lever. and block in assembly when thedoor is" closed anduntil the door is suiiiciently open to permit 1nove- 'inent of the leverbetween the overhanging portions, these overhanging portions havingopposing edges that areobliquely arranged and spaced apart su'fiicientlylever to be moved throughthe spacebetween these opposing edges when thelever has been suiiiciently swung ina door openingdirection. to bring itintotalignment or. registry with the space. between said: opposingoblique edges of said over ianging portions of the block. Fig. 6illustrates in dotted lines the position/to which the-lever may he swungin order that it-inay be passed: into or out of the channel lOthroughthe space between the opposing oblique edges of the channeloverhanging portions 18 and: 1%.

\Vhen the lever is moved out of the channelto becoine free of the block9 such block may be employed as a handle further to that the blockbetter function as a handle I give it a hinged connection 2113-15 with.a block supporting iron 16 that is bolted to the door. \Vhenthe door isin a closed posishift the door and in order tion the lever is overhunghy both overhanging parts 13 and 14 of'the bloclr to enable the lever totake part in holding the door closed, these overhangingparts 13 and 14also serving to keep the lever in its own plane in which it may befurther held by means of the hook 17 that is provided upon the leverThis block is.

to a permit the and the eye 18.:passing through the opening 19 in thelever and through which the free end of the hook is also projected. Thehook maybe provided with an apertured car 20 and the free end of thehook may also be apertured to enable a sealing wire 21 to be assernhledwiththe hook after the free end of the hook has been passed through theeye 18, the ends of thewire 21ha-vin g any usual.
